Purpose:
-
Extract specified variables from compressed history files and write the delta values to the extracted directory.
Enter:
-
xtrs <label_name1> <label_name2> … [start=filename] [end=filename] [start_time=ANSI time] [end_time=ANSI time] [dir=directory] [files=file filter]
Where:
-
label_nameX
Specify up to 32 labels to extract from compressed history files.
start=filename
Optional. Specify the starting file name.
end=filename

The above example extracts the 2 variables from all of the compressed history files. This may take several minutes to accomplish.xtrs RPM TORQUE oil_p start=200201010000 end=200201020000
The above example extracts the RPM, TORQUE, and oil_p variables for the 24 hour period on Jan 1, 2002.
Notes:

Limiting the extraction to a specified time period can reduce processing time if only a known range is of interest.
